Answer this question truthfully
### Question: What causes Coronary heart disease?
### Response: Coronary heart disease is usually caused by a condition called atherosclerosis, which occurs when fatty material and other substances form a plaque build-up on the walls of your arteries. This causes them to get narrow. As the coronary arteries narrow, blood flow to the heart can slow down or stop. This can cause chest pain (stable angina), shortness of breath, heart attack, and other symptoms, usually when you are active.
Coronary heart disease (CHD) is the leading cause of death in the United States for men and women.
